Hello,

Is there a real improvement of torque with this set ?
Is it easy to add/remove it ?

Thanks for your advice,

There is a price to pay with torque cones.....they will help in the lower rpm area with a pipe that over scavenges (like drag pipes) the exhaust but it will rob much more on the top end than it adds to the lowend.
If you put them in a pipe that scavenges good already (280 to 300 feet per second) you will kill the performance of the engine from too much restriction.
